0.96 Inch OLED Display Module (Blue) | I2C Interface 128×64 Pixel
Sharp, Bright, and Compact. This 0.96-inch OLED screen delivers incredibly crisp blue text on a black background. Unlike standard LCDs, it doesn't need a backlight, making it thinner and more energy-efficient. It uses the I2C interface, so you only need 2 wires to control it!
-
Resolution: 128 x 64 Pixels.
-
Color: Blue Text on Black Background.
-
Interface: I2C (Only 4 pins).
- Controller: SSD1306 (Standard Library).
- Best For: Smart Watches, Weather Stations, and Battery Monitors.
1-Channel 12V Relay Module | For Car Electronics & Solar Projects
The standard relay for 12V systems. Unlike the standard 5V Arduino relay, this module is designed to run directly on 12V power. It is perfect for automotive projects, car security systems, and solar setups where only 12V is available.
-
Coil Voltage: 12V DC.
-
Trigger: Low Level (Connect Signal to GND to switch ON).
-
Max Load: 250V AC / 10A.
-
Best For: Car Alarms, Central Locks, Horns, and Solar Inverters.
1-Channel 5V Relay Module | Low Level Trigger for Arduino
Control high voltage safely. This single-channel relay allows your Arduino to switch high-power devices like light bulbs, water pumps, or fans. It isolates your microcontroller from the high voltage using an internal switch.
-
Trigger: Low Level (Connect Signal to GND to turn ON).
-
Max Load: 250V AC / 10A.
-
Indicators: Red Power LED + Green Status LED.
-
Best For: Smart Lamps, Fan Control, and Simple Automation.
1.3 Inch OLED Display Module (Blue) | I2C SH1106 Screen 128×64
Bigger, clearer, and easier to read. The 1.3-inch OLED gives you 35% more screen area than the standard 0.96-inch version. It features the exact same 128x64 resolution but with larger pixels for better visibility from a distance.
-
Size: 1.3 Inch (Diagonal).
-
Controller: SH1106 (Requires specific library setting).
- Interface: I2C (4 Pins).
- Best For: Digital Dashboards, Smart Meters, and Menus.
